ABSTRACT

OBJECTIVE@#To explore the mechanisms of Dangua Recipe (DGR) in improving glycolipid metabolism based on transcriptomics.@*METHODS@#Sprague-Dawley rats with normal glucose level were divided into 3 groups according to a random number table, including a conventional diet group (Group A), a DGR group (Group B, high-calorie diet + 20.5 g DGR), and a high-calorie fodder model group (Group C). After 12 weeks of intervention, the liver tissue of rats was taken. Gene sequence and transcriptional analysis were performed to identify the key genes related to glycolipid metabolism reflecting DGR efficacy, and then gene or protein validation of liver tissue were performed. Nicotinamide phosphoribosyl transferase (Nampt) and phosphoenolpyruvate carboxykinase (PEPCK) proteins in liver tissues were detected by enzyme linked immunosorbent assay, fatty acid synthase (FASN) protein was detected by Western blot, and fatty acid binding protein 5 (FABP5)-mRNA was detected by quantitative real-time polymerase chain reaction. Furthermore, the functional verification was performed on the diabetic model rats by Nampt blocker (GEN-617) injected in vivo. Hemoglobin A@*RESULTS@#Totally, 257 differential-dominant genes of Group A vs. Group C and 392 differential-dominant genes of Group B vs. Group C were found. Moreover, 11 Gene Ontology molecular function terms and 7 Kyoto Encyclopedia of Genes and Genomes enrichment pathways owned by both Group A vs. Group C and Group C vs. Group B were confirmed. The liver tissue target validation showed that Nampt, FASN, PEPCK protein and FABP5-mRNA had the same changes consistent with transcriptome. The in vivo functional tests showed that GEN-617 increased body weight, HbA@*CONCLUSION@#Nampt activation was one of the mechanisms about DGR regulating glycolipid metabolism.

ABSTRACT

OBJECTIVE@#To analyze the clinical phenotype and genetic basis for a Chinese pedigree affected with coagulation factor XI (FXI) deficiency.@*METHODS@#Activated partial thromboplastin time (APTT) and other blood coagulation factors, and activities of FXI:C and other relevant coagulation factors for a large Chinese pedigree including 6 patients from 3 generations were determined on a Stago automatic coagulometer. The FXI:Ag was determined with an ELISA method. All exons and flanking regions of the F11 gene were subjected to Sanger sequencing. ClustalX-2.1-win software was used to analyze the conservation of amino acids. Pathogenicity of the variants was predicted with online bioinformatics software including Mutation Taster and Swiss-Pdb Viewer.@*RESULTS@#The APTT of the proband was prolonged to 94.2 s. The FXI:C and FXI:Ag were decreased to 1% and 1.3%, respectively. The APTT of her father, mother, son and daughter was 42.1 s, 43.0 s, 42.5 s and 41.0 s, respectively. The FXI:C and FXI:Ag of them were almost halved compared with the normal values. The APTT, FXI:C and FXI:Ag of her husband were all normal. Genetic testing revealed that the proband has carried a heterozygous missense c.1103G>A (p.Gly350Glu) variant in exon 10 and a heterozygous missense c.1556G>A (p.Trp501stop) variant in exon 13 of the F11 gene. The father and daughter were heterozygous for the c.1103G>A variant, whilst the mother and son were heterozygous for the c.1556G>A variant. Both Gly350 and Trp501 are highly conserved among homologous species, and both variants were predicted to be "disease causing" by Mutation Taster. Protein modeling indicated there are two hydrogen bonds between Gly350 and Phe312 in the wild-type, while the p.Gly350Glu variant may add a hydrogen bond to Glu and Tyr351 and create steric resistance between the two, both may affect the structure and stability of protein.@*CONCLUSION@#The c.1103G>A and c.1556G>A compound heterozygous variants probably underlay the pathogenesis of congenital FXI deficiency in this pedigree.

ABSTRACT

Since the concept of "safe area" put forward by Lewinnek, it has been widely recognized. While in recent years, many scholars have found that even if the acetabular prosthesis was placed on the "safe area", there were still many unexplained dislocation after total hip arthroplasty. And scholars began to question whether the "safe area" is really suitable for all patients. Spinal degeneration, deformity, lumbar fusion, etc. will lead to spine sagittal imbalance and changes in pelvic activity, which could lead to changes in acetabular orientation, and ultimately lead to edge loading, wear, impact, and even dislocation after total hip replacement. From the perspective of wear, impact and dislocation, it is determined by the functional positioning of the acetabular cup, not the anatomical positioning. The anatomical positioning and functional positioning of the neutral pelvic acetabular cup in the standing position can be considered equivalent. For pelvic rotation more than 20°, functional placement needs to be considered. In recent years, as the understanding of the internal relationship between the spine-pelvis-hip joint has become more and more profound, some scholars further classify the hip-spine relationship according to whether the spine is stiff or deformed, and propose corresponding acetabulums according to different types of hip-spine relationships The function of placement, so as to achieve a stable artificial hip joint. Therefore, it is of great significance to fully assess whether the patient's sagittal plane is balanced before surgery to guide artificial hip replacement surgery.

ABSTRACT

Objective:To investigate the effect of eccentric exercise training on knee function and neuromuscular control in patients with patellofemoral pain syndrome. Methods:From September, 2016 to September, 2019, 39 outpatients with patellofemoral pain syndrome visiting our hospital were randomly divided into control group (n = 19) and experimental group (n = 20). Both groups received routine rehabilitation, while the experimental group received eccentric training of quadriceps femoris in addition, for eight weeks. They were assessed with Visual Analogue Scale (VAS) of pain, Lysholm score, while the acceleration time was measured with Isokinetic Testing and Training System, and stability index with Dynamic Balance Tester. Results:The VAS score, acceleration time of all the muscles, and overall, anterior-posterior and medial-lateral stability indexes decreased (t > 2.521, P < 0.05), and the Lysholm score increased (|t| > 13.628, P < 0.001) in both groups after treatment, while the VAS score, acceleration time of all the muscles, overall and anterior-posterior stability indexes were less (|t| > 2.174, P < 0.05), and the Lysholm score was more (t = 11.947, P < 0.001) in the experimental group than in the control group. Conclusion:Eccentric exercise training of quadriceps femoris is effective on pain, knee function and neuromuscular control for patients with patellofemoral pain syndrome.

ABSTRACT

Objective To investigate the level of cadmium(Cd)in commercial aquatic products in Xiacheng District, Hangzhou. Methods We randomly collected 293 aquatic products which belonged to six aquatic animals in the markets in Xiacheng District to determine the content of Cd. It was further evaluated by single factor pollution index(PI)according to the standard GB 2762-2017. In 11 samples of swimming crabs, Cd was examined in the different parts. Results There was no significant difference in the content of Cd between the samples collected in the markets and those in the supermarkets. It significantly differed in the samples of different aquatic animals(P < 0.05). The prevalence of Cd that exceeded the standard was as follows: seawater crustaceans(28.6%) > cephalopods(11.1%) > freshwater crustaceans(8.4%) > bivalves(6.9%). However, it was not excessive in the samples of fish. The mean level of Cd in the seawater crustaceans was 0.466 3 mg/kg, which resulted in the proportion of the samples that were excessive being 28.6%. Particularly, the mean level in sea crab was as high as 1.101 mg/kg with the proportion being 66.7%. In the samples of swimming crabs, there was a significant difference in the prevalence of Cd between swimming crab gonads and crab chests or legs(P > 0.05), while no statistical difference between crab chests and legs(P > 0.05). Conclusion The content of Cd in the aquatic products may be excessive in Xiacheng District, which warrants additional regulatory efforts to food safety. The public should reduce the consumption of aquatic products with high content of Cd.

ABSTRACT

Objective:To investigate the clinical efficacy of plasma exchange combined with dual plasma molecular adsorption system (PE+ DPMAS) in treating patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 114 HBV-ACLF patients admitted to The Affiliated Hospital of Southwest Medical University in Luzhou City and treated with PE+ DPMAS from June 2014 to January 2018 were included. According to different basis of liver diseases, there were type A, type B and type C. The laboratory data and model for end-stage liver disease (MELD) of patients before PE+ DPMAS and 48 h after treatment, and the prognosis of patients at 90 d were retrospectively analyzed. Independent sample t test, paired sample t test, nonparametric test, variance analysis and chi-square test were used for statistical analysis. Results:The clinical stages among patients with type A (22 cases), type B (39 cases) and type C (53 cases) were mainly early (seven, 17, 22 cases) and mid-stages (eight, 14, 20 cases). Before PE+ DPMAS, alanine aminotransferase (ALT), prealbumin (pAlb), albumin (Alb), creatinine (Cr), total bilirubin (TBil), prothrombin time (PT), international normalized ratio (INR), prothrombin activity (PTA), and MELD were all not statistically different among the patients in the three groups (all P>0.05). After PE+ DPMAS treatment, ALT, TBil, PT, INR, MELD, pAlb, Alb, and PTA in patients with type A were statistically different compared with those before treatment ( Z=5.104, t=5.555, 4.974, 4.481, 7.984, -5.396, -2.784 and -6.752, respectively, all P<0.05). ALT, TBil, PT, INR and MELD in patients with type B were significantly decreased, while pAlb and PTA were significantly increased after treatment ( Z=-5.428, t=4.867, 4.405, 4.179, 6.186, -6.290 and -4.533, respectively, all P<0.01). ALT, pAlb and TBil in patients with type C after PE+ DPMAS treatment were significantly different from those before treatment ( Z=-5.723, t=-2.525 and 2.462, respectively, all P<0.05). There was no statistically significant difference in Cr of the three groups before and after treatment (all P>0.05). The patients with type A had the shortest hospital stay ((17.95±5.92) d), while the patients with type C had the longest stay ((25.77±7.02) d). The hospital stay of patients with type B was (21.79±6.72) d. The difference was statistically significant ( F=11.317, P<0.01). After 90 d follow-up, four patients (18.18%) with type A died, nine patients (23.08%) with type B died, and 25 patients (47.17%)with type C died. The difference was statistically significant ( χ2=8.615, P=0.013). Conclusion:HBV-ACLF patients with type A and type B have better prognosis after PE+ DPMAS treatment compared to patients with type C who are in the decompensated stage of liver cirrhosis.

ABSTRACT

Complete healing of the intestinal mucosa is the most ideal goal in the treatment of inflammatory bowel disease (IBD). The intestinal mucosa healing not only significantly alters the course of the disease and relieves clinical symptoms, but also markedly reduces the occurrence of complications and prevents recurrence of IBD. As chronic inflammation associated with peptic ulcer damage is the main pathological feature of IBD, clinical treatment is mainly based on anti-inflammatory therapy, but such therapy cannot promote the healing of the intestinal mucosa of patients. Therefore, how to achieve long-term remission of IBD is still an urgent challenge. In the process of intestinal mucosal repair, the polarization of macrophages maintains the homeostasis of the intestinal microenvironment, which is a representative process that promotes mucosal inflammatory-repair. It is a key part of initiating tissue regeneration that should not be underestimated. In this paper, we reviewed the literature of the past decade, focusing on the promotion of intestinal mucosal healing in IBD. The discussion will highlight the importance and feasibility of regulating macrophages to promote intestinal mucosal repair. Following this thought, we discuss the shortcomings of current clinical treatments and summarize the relevant drugs which have potential to promote intestinal mucosal repair. The aim is to provide effective potential drugs and therapeutic targets for the treatment of IBD.

ABSTRACT

Objective:To compare the therapeutic efficacies of Wujiwan at two different compatibilities (No.1 and No.2) on irritable bowel syndrome (IBS) based on neuro-endocrine-immune network, and provide a theoretical basis for the treatment based on syndrome differentiation in traditional Chinese medicine (TCM). Method:The chronic animal model of IBS with visceral hypersensitivity was established by colon irritation via percutaneous transluminal coronary angioplasty (PTCA) in suckling rats. The animals were randomly divided into a control group, a model group, a dicetel group (0.01 g·kg<sup>-1</sup>), low- (0.335 g·kg<sup>-</sup><bold><sup>1</sup></bold>), medium- (0.67 g·kg<sup>-</sup><bold><sup>1</sup></bold>), and high-dose (1.34 g·kg<sup>-</sup><bold><sup>1</sup></bold>) No. 1 Wujiwan groups, and low- (0.385 g·kg<sup>-</sup><bold><sup>1</sup></bold>), medium- (0.77 g·kg<sup>-</sup><bold><sup>1</sup></bold>), and high-dose (1.54 g·kg<sup>-</sup><bold><sup>1</sup></bold>) No. 2 Wujiwan groups. The thresholds of abdominal elevation and bow back elevation were evaluated to detect the effect of Wujiwan on intestinal sensitivity of IBS. The density of mast cells (MC) in the colonic tissue of model rats was detected by the modified toluidine blue staining method. The concentrations/positive expression of 5-hydroxytryptamine (5-HT), substance P (SP), somatostatin (SS), and vasoactive intestinal peptide (VIP) in the blood/colon tissue were detected by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) assay. Result:There was no significant difference in body weight among different groups. Compared with the control group, the model group exhibited decreased thresholds of abdominal elevation and bow back elevation (<italic>P<</italic>0.01), increased density of MCs in the colon tissue (<italic>P<</italic>0.05), up-regulated levels of 5-HT, SP, and SS in the blood and colon tissue (<italic>P<</italic>0.05, <italic>P<</italic>0.01), and elevated VIP level in the colon tissue (<italic>P</italic><0.05). Compared with the model group, Wujiwan at different compatibilities could increase the thresholds of abdominal elevation and bow back elevation (<italic>P</italic><0.01), diminish the count of MC in the colon tissue (<italic>P</italic><0.05), and reduce the levels of 5-HT, SP, SS, and VIP (<italic>P</italic><0.05). As demonstrated by the comparison of No. 1 and No. 2 Wujiwan, No. 1 was superior to No. 2 in reducing the concentrations of 5-HT, SP, and SS in the blood, especially in 5-HT (<italic>P</italic><0.01). No significant difference between No. 1 and No. 2 in reducing 5-HT positive expression in the colon tissue was observed. Compared to the No. 1 Wujiwan, No. 2 significantly reduced SP expression, and the intensity and range of SS expression in the colon tissue in the No. 2 groups were smaller than those in the No. 1 groups (<italic>P</italic><0.05). Conclusion:Wujiwan at different compatibilities was capable of improving gastrointestinal hormone disorder of IBS to reduce intestinal sensitivity. In terms of systemic effect, No. 1 was superior to No. 2, while in terms of local effect, No. 2 was advantageous. No. 1 Wujiwan was superior to No. 2 in the effect on intestinal dynamics, while No. 2 had an advantageous effect on intestinal sensation over No. 1.

ABSTRACT

Lung cancer is a malignant tumor with high incidence and high mortality, posing a great threat to human health. Neovascularization may be one of the important mechanisms of lung cancer. The growing lung cancer cells can obtain necessary nutrients from the newly formed blood vessels, thereby causing the spread and metastasis of lung cancer. Nowadays, anti-angiogenic drugs are commonly used in western medicine in addition to surgery,radiotherapy, chemotherapy, and immunotherapy. However, the resulting adverse reactions such as thrombosis, hypertension, diarrhea, and cardiotoxicity have seriously affected the quality of life of patients. As the recognition of angiogenesis deepens, the selection of lung cancer treatment options has become a research hotspot and difficulty in the field of lung cancer treatment. In traditional Chinese medicine(TCM), angiogenesis is believed to fall into the category of “collateral disease”. The invasion of external pathogens and deficiency of healthy Qi will cause visceral dysfunction, which can be gradually followed by Qi obstruction and blood stasis and phlegm-turbidity congesting the collaterals. As a result, the collateral function will be damaged, providing favorable conditions for the occurrence of lung cancer. More and more modern studies have confirmed that TCM is able to inhibit angiogenesis in the lung cancer, thereby resisting the tumor. In addition, by virtue of the unique advantages, TCM effectively reduces adverse reactions, enhances the efficacy, and improves the living conditions of patients. Moreover, it can synergize with other western medicine therapies in the treatment of lung cancer, exhibiting a wide application prospect. This paper summarizes the mechanisms of TCM in inhibiting angiogenesis of lung cancer reported in relevant experimental research, hoping to provide reference for the optimization of clinical treatment strategies for lung cancer.

ABSTRACT

Psoriasis is an autoimmune disease presented in the context of inflammation, and it mainly results from proliferation and differentiation defects of keratinocytes and abnormal immune response. However, some cellular and molecular mechanisms remain unclear. Although a variety of drugs and physiotherapies are applicable to this disease, they can only be utilized for a short-term period considering their transient effect, high cost, and serious adverse reactions. It is difficult to achieve satisfactory long-term results in the treatment of psoriasis. With the development of network pharmacology and molecular biology and the modernization of traditional Chinese medicine (TCM), the multi-component and multi-target characteristics of TCM have become prominent, promoting the in-depth research on TCM by doctors and scholars. Nevertheless, there is no detailed summarization on the mechanisms of TCM in interfering with T helper 17 (Th17)/regulatory T (Treg) cell balance to prevent and treat psoriasis. After reviewing the recent literature data, this paper has found that Chinese herbal monomers, active ingredients, and compounds obviously regulate the Th17/Treg axis in psoriasis. Th17 cells have a pro-inflammatory effect, while Treg cells are responsible for maintaining peripheral tolerance. They function in a mutually exclusive manner, and maintaining the Th17/Treg balance helps to effectively reduce inflammatory reaction and regulate immune homeostasis. As revealed by a series of clinical and experimental studies carried out based on the Th17/Treg axis in psoriasis, reducing the percentage of Th17 cells,increasing the percentage of Treg cells,and regulating the levels of related cytokines and transcription factors are conducive to alleviating inflammation and regaining immune homeostasis,which has provided new ideas for further elucidating the pathological mechanism of psoriasis and alternative plans for developing new treatments against psoriasis.

ABSTRACT

Cells in the arterial wall are constantly subjected to the shear stress generated by the blood flow. Shear stress plays a pivotal role in the formation of atherosclerosis. The endothelial cells located between the blood and the vessel wall have a unique response to the shear stress of the blood flow, which can convert mechanical stimulation into intracellular signals, thereby affecting the pathological process of atherosclerosis. Endothelial function is not only regulated by hormones, growth factors and other biochemical substances, but also affected by mechanical forces such as blood flow shear stress. Physiologically, shear stress can play an anti-atherosclerotic role in maintaining the homeostasis of endothelial cells. Pathological shear stress will lead to endothelial dysfunction and promote the progression of atherosclerosis. Under the mediation of different shear stress, the endothelial function can be regulated through epigenetic pathways or mechanically sensitive cation channels. Therefore, it is necessary to understand how various signal transduction pathways are affected by pathological shear stress, so as to cause endothelial dysfunction and atherosclerosis. Traditional Chinese medicine(TCM) has been increasingly recognized for its curative effect in treating atherosclerosis, with the advantages of few side effects, multiple targets and multiple mechanisms. In recent years, the understanding of the anti-atherosclerosis mechanism of TCM mediated by shear stress has gradually deepened. This review will take endothelial function as the breakthrough point, systematically sort out the influence of shear stress on the pathological process of atherosclerosis and the related molecular mechanisms. Meanwhile, it is the first time to summarize the latest research progress of Chinese medicine against shear stress damage by sorting out the existing literature. This article mainly clarify the relationship between shear stress, endothelial function, atherosclerosis and TCM, in order to provide a theoretical basis for the clinical treatment and pathological mechanism of atherosclerosis.

ABSTRACT

Objective:To establish an ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) for determining the plasma concentrations of 10 active ingredients in Wujiwan at different time points after oral administration, and to compare the pharmacokinetic characteristics between normal rats and rats with chronic visceral hypersensitive irritable bowel syndrome (CVH-IBS). Method:CVH-IBS rat model was prepared by the neonatal rat colon percutaneous transluminal coronary angioplasty (PTCA) balloon stimulation method. After intragastric administration of Wujiwan (0.245 g·kg<sup>-1</sup>), blood was collected from the jugular vein at different time points, and the plasma concentrations of 10 active ingredients (berberine hydrochloride, palmatine hydrochloride, coptisine hydrochloride, jatrorrhizine hydrochloride, epiberberine, dihydroberberine, evodiamine, evodine, paeoniflorin, albiflorin) in Wujiwan was detected simultaneously by UPLC-MS/MS, the pharmacokinetic parameters of each component in normal rats and CVH-IBS rats were calculated. Result:The established UPLC-MS/MS could sensitively and accurately detect the plasma concentrations of 10 active ingredients of Wujiwan in rats. Compared with the normal group, the absorption rates of these 10 active ingredients of Wujiwan in the blood of CVH-IBS rats all decreased to a certain extent, and the peak time (<italic>t</italic><sub>max</sub>) was prolonged. Among them, the <italic>t</italic><sub>max</sub> of berberine hydrochloride and jatrorrhizine hydrochloride were significantly prolonged from 54 minute and 39 minute to 90 minute, respectively (<italic>P</italic><0.05, <italic>P</italic><0.01). Area under the plasma concentration-time curve (AUC<sub>0-</sub><italic><sub>t</sub></italic>) of each component increased, and evodiamine and paeoniflorin were significantly different (<italic>P</italic><0.05,<italic> P</italic><0.01). The clearance rates (CL/<italic>F</italic>) of these 10 active ingredients were all decreased, among which berberine hydrochloride, palmatine hydrochloride and evodiamine had significant differences (<italic>P</italic><0.05, <italic>P</italic><0.01). Conclusion:There are significant differences in the pharmacokinetic behavior of the active ingredients in Wujiwan between normal rats and CVH-IBS rats, which may be related to the destruction of microstructure of intestinal epithelial cells and the change of activity of liver enzymes under the pathological state of IBS.

Then the stability of PvQ was also analyzed for its anticoagulant activity at different pH and temperature. Result:The PvQ was successfully enriched and its activity was determined to have significant fibrinolytic and anticoagulant activities. And the result of <italic>in vitro</italic> thrombolysis assay revealed that PvQ could hydrolyze more than 80% of thrombus after 5 h of incubation at 37 ℃. In addition, the changes of temperature and pH had significant effects on antithrombotic activity, and this study showed that PvQ was rapidly inactivated at ≥60 ℃ or in acidic conditions (pH<7). While, the activity of PvQ was unaffected or less affected at ≤50 ℃ and under alkaline conditions. Conclusion:A feasible preparation method of PvQ is established, and it can affect fibrin and fibrinogen at the same time, thus exerting a dual fibrinolytic effect and possessing significant fibrinolytic and anticoagulant activities. It provides a scientific interpretation for the treatment of thrombotic diseases by PvQ and a reference for the development of antithrombotic protein products of Pheretima.

ABSTRACT

This study aimed to investigate the effect and the possible mechanism of Shenlian( SL) extract on tumor necrosis factor-α( TNF-α)-induced ECV304 injury. After the establishment of TNF-α-induced ECV304 cells injure model,MTT assay was used to detect cell viability and the level of reactive oxygen species( ROS) was measured by flow cytometry. The contents of superoxide dismutase( SOD),malondialdehyde( MDA),nitric oxide( NO),endothelin-1( ET-1) and interleukin-1β( IL-1β) in the supernatant were detected by biochemical method and enzyme linked immunosorbent assay( ELISA). The expression levels of apoptosis-related proteins B-lymphoma-2 gene( Bcl-2),Bcl-2 associated X protein( Bax),caspase-3,caspase-9 and nuclear factor E2 associated factor2( Nrf2)/Kelch like epichlorohydrin associated protein-1( Keap1) signaling pathway related proteins Nrf2,Keap1,quinone oxidoreductase( NQO1) and heme oxygenase 1( HO-1) were detected by Western blot. The results showed that 50 μg·L-1 TNF-α significantly damaged ECV304 cells,induced the impairment of cell viability( P<0. 01),the increase of ROS production,the decrease of SOD activity,and the increase of MDA,NO,ET-1 and IL-1β( P<0. 01),meanwhile,it caused the up-regulation of Keap1,caspase-9 and Bax protein expression,and down-regulation of NQO1 and Bcl-2 protein expression( P<0. 05) compared with the control group.Compared with the model group,SL extract reduced the damage of ECV304 cells induced by TNF-α,improved cell viability,reduced ROS production,increased SOD activity and decreased MDA,NO,ET-1,IL-1β content( P<0. 01 or P<0. 05). In addition,SL extract also down-regulated the protein expression levels of Keap1,caspase-3,caspase-9 and Bax,and increased the protein expressions of Nrf2,NQO1,HO-1 and Bcl-2( P<0. 01 or P<0. 05). The above results indicate that SL extract can provide protective effect on ECV304 cells injury induced by TNF-α,alleviate oxidative stress injury,inflammation and apoptosis,and its mechanism may be related to regulating Nrf2/Keap1 signaling pathway.

ABSTRACT

In this study, patients with prehypertensive liver-fire hyperactivity syndrome(LFHS) were selected as the research objects. The plasma samples of healthy volunteers and patients with prehypertensive LFHS were analyzed by non-targeted metabolomics based on UPLC-Q-Exactive MS. The differential biomarkers and metabolic pathways were screened out by multivariate statistics and metabolic pathway analysis, which revealed the characteristics of metabolic patterns of the syndrome. Thirty-three potential biomarkers such as androsterone and lysophosphatidylcholine and 16 related metabolic pathways such as steroid hormone metabolism and lipid metabolism were identified, and a partial least squares-discriminant analysis(PLS-DA) model of traditional Chinese medicine(TCM) syndromes was preliminarily constructed: Y =-0.070X_(13)-0.006X_8+ 0.040X_5-0.152X_1+0.131X_(10)+0.036X_(11)+0.043X_(23)+0.076X_(16)+0.132X_(20)+0.081X_(19)-0.101X_(31)+0.082X_(15)-0.038X_9+0.079X_(24). The predictive value of the model was 88.1%, and the explanatory power was 88.4%. In this study, the characteristic metabolic pattern of the prehypertensive LFHS was distinguished and revealed by metabolomics. The constructed PLS-DA model is expected to provide an objective basis for the identification of TCM syndromes in prehypertension, and inspiration for exploring the biological basis of TCM syndromes at small-molecular and overall levels.

ABSTRACT

BACKGROUND@#The global pandemic coronavirus disease 2019 (COVID-19) has become a major public health problem and presents an unprecedented challenge. However, no specific drugs were currently proven. This study aimed to evaluate the comparative efficacy and safety of pharmacological interventions in patients with COVID-19.@*METHODS@#Medline, Embase, the Cochrane Library, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/SARS-CoV. Random-effects network meta-analysis within the Bayesian framework was performed, followed by the Grading of Recommendations Assessment, Development, and Evaluation system assessing the quality of evidence. The primary outcome of interest includes mortality, cure, viral negative conversion, and overall adverse events (OAEs). Odds ratio (OR) with 95% confidence interval (CI) was calculated as the measure of effect size.@*RESULTS@#Sixty-six RCTs with 19,095 patients were included, involving standard of care (SOC), eight different antiviral agents, six different antibiotics, high and low dose chloroquine (CQ_HD, CQ_LD), traditional Chinese medicine (TCM), corticosteroids (COR), and other treatments. Compared with SOC, a significant reduction of mortality was observed for TCM (OR = 0.34, 95% CI: 0.20-0.56, moderate quality) and COR (OR = 0.84, 95% CI: 0.75-0.96, low quality) with improved cure rate (OR = 2.16, 95% CI: 1.60-2.91, low quality for TCM; OR = 1.17, 95% CI: 1.05-1.30, low quality for COR). However, an increased risk of mortality was found for CQ_HD vs. SOC (OR = 3.20, 95% CI: 1.18-8.73, low quality). TCM was associated with decreased risk of OAE (OR = 0.52, 95% CI: 0.38-0.70, very low quality) but CQ_HD (OR = 2.51, 95% CI: 1.20-5.24) and interferons (IFN) (OR = 2.69, 95% CI: 1.02-7.08) vs. SOC with very low quality were associated with an increased risk.@*CONCLUSIONS@#COR and TCM may reduce mortality and increase cure rate with no increased risk of OAEs compared with standard care. CQ_HD might increase the risk of mortality. CQ, IFN, and other antiviral agents could increase the risk of OAEs. The current evidence is generally uncertain with low-quality and further high-quality trials are needed.

ABSTRACT

This study investigated the effects of ginkgolide B on the long-chain fatty acid metabolism-related enzyme protein peroxisome proliferators-activated receptors α (PPARα), long-chain specific acyl-CoA dehydrogenase (LCAD), carnitine palmitoyl transterase-1 (CPT-1), and acyl coenzyme A oxidase 1 (ACOX1) expression in the liver of rats with non-alcoholic fatty liver disease (NAFLD). All the animal welfare and experimental procedures are in accordance with the regulations of the Animal Ethics Committee of Yunnan University of Traditional Chinese Medicine. After successfully building the rat model of non-alcoholic abnormal liver disease, the rats were divided into the model group, the simvastatin group, and the low-dose, middle-dose, and high-dose groups of ginkgolide B according to random number method, and were given corresponding drug treatment 4 weeks. We detected liver pathological indicators and determined blood lipids, transaminase and anti-oxidation indexes. Western blot and RT-PCR assays were used to detect the protein and mRNA levels of PPARα, LCAD, CPT-1, and ACOX1 in livers. The results showed that: ① the liver histopathology showed that the liver slices of the model group had obvious structural disorder, the nucleus was squeezed, and there were obvious fat vacuoles. The treatment groups improved significantly compared with the model group; ② compared with the normal group, the liver function and blood lipid indexes of the model group increased significantly, while the anti-oxidation indexes decreased significantly. Compared with the model group, each treatment groups were significantly improved; ③ compared with the normal group, the protein and mRNA expression levels of PPARα, ACOX1, CPT-1, and LCAD in the model group were significantly reduced, compared with the model group, those indexes in the treatment groups were significantly up-regulated. This study found that ginkgolide B could regulate the expression of long-chain fatty acid metabolism-related proteins PPARα, ACOX1, CPT-1, and LCAD, meanwhile improve the body's antioxidant capacity, thereby reduce blood lipids, further improve liver function and protect the liver.

ABSTRACT

Objective:To investigate any change in the effective connectivity between the bilateral anterior central gyruses after transcranial magnetic stimulation (TMS).Methods:Twenty-one healthy subjects were examined using resting state functional magnetic resonance imaging (rs-fMRI) before and after receiving continuous theta burst stimulation (cTBS). The brain atlas of the Institute of Automation of the Chinese Academy of Sciences was used for fine partitioning of the bilateral anterior central gyruses. Granger causality analysis was used to compare any changes in the effective connectivity between them.Results:After the cTBS inhibited the right M1 area, significant changes in effective connectivity among the sub-regions of the bilateral M1 area were observed. The effective connectivity of the right upper limb to the left upper limb and the left head to face were weakened, while that of the left upper limb to the right head, as well as of the face to the right upper limb was enhanced.Conclusion:For people whose right M1 area has been inhibited by cTBS, the effective connectivity changes in both upper limb functional areas of the M1 region reflect inter-hemispheric inhibition. Opposite changes were found in the trunk and upper limbs.
